Leo apologizes for his absence at VIXX's fan sign event

Previously, Leo was unable to attend VIXX's fan sign event on April 26 due to health issues. For his worried fans, Leo posted a message on his Twitter.

He said, "Our Starlights must've been surprised by the news. I'm sorry, not because I'm sick but because I made you guys worry~ And I'm really really sorry to Starlights who came to the fan sign event today! I'll try my best to not be sick and recover fast. ^^ I'm sorry for causing concerns. Sweet dreams!"
